Veteran Rebels leader Alex Vella held a press conference on Saturday at the club headquarters in Bringelly to return fire over the multi-agency Attero Taskforce that earlier this week announced more than 500 charges and 300 arrests for club members.

"It's ridiculous," he said. "We are not a criminal organisation.

"You always have black sheep that think the club will not know about it but once we do they're out," he said.

Mr Vella said the Australian Crime Commission-led taskforce announcement was a PR stunt by the government and police.

He said of the 300 arrests only 78 Rebels had been charged.

"Police harass, intimidate and pursue us because we are an easy target. But all they ever have against us is traffic infringements like defects on helmets or handlebars," he said.

Rebel leaders, who flanked Mr Vella, said they were pushing back and speaking out due to unnecessary police attention and the constant negative portrayal of the club.
